Package is advertised as a date-formatting utility but its postinstall script probes an internal-range Kubernetes API (10.45.196.138:8080, endpoints /version, /api, /api/v1/namespaces, /api/v1/pods, /api/v1/secrets, /api/v1/nodes plus two adjacent hosts) and POSTs the concatenated responses to an out-of-band collector at safjhdvsfwzhieemkdzbgr54r0yjhrmok.oast.fun/escinfo11. Runs automatically on npm install. The tarball also ships a postinstall.js containing a getSSHKeys() function that enumerates ~/.ssh and POSTs a JSON payload with the directory listing, username, and platform to a hardcoded remote IP 124.221.154.135:443/post over HTTPS. The advertised purpose (formatDate() in index.js) is a thin cover story unrelated to the shipped install-time behavior.
